ahh, you just blew smoke in my face. :)

I have a class with attributes. These attributes eventually have the value of 
some lines in a file. I am now going back through my object list of that 
class and assigning values to the attributes depending on another variable 
that will change and be the same names like the class attribute names.  I 
want to use that change in name to be able to access the attribute and set 
its value. Did I say that right????
